From the Guidelines
Hypertension management in patients with advanced chronic kidney disease (CKD) should prioritize a target mean systolic blood pressure of <120 mm Hg, if tolerated, for those aged ≥50 years and/or with CKD G3–G5, as recommended by the most recent guidelines 1.
Key Considerations
- For patients with advanced CKD (stages 4-5), with or without hemodialysis (HD), the management of hypertension requires careful consideration of both blood pressure targets and medication selection.
- First-line medications typically include angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), which provide renoprotective effects by reducing intraglomerular pressure and proteinuria, as supported by recent guidelines 1.
- The choice of antihypertensive agent can also be affected by the presence or absence of CKD with or without proteinuria and by lifestyle modifications, as suggested by expert opinions 1.
Medication Selection
- ACEIs like lisinopril (10-40 mg daily) or ARBs such as losartan (50-100 mg daily) are recommended as first-line treatments.
- Calcium channel blockers like amlodipine (5-10 mg daily) are particularly useful in this population as they don't require dose adjustment in kidney failure.
- Beta-blockers such as metoprolol (25-200 mg daily) are beneficial, especially in patients with concurrent heart failure or coronary artery disease.
Lifestyle Modifications
- Lifestyle interventions, including dietary and lifestyle modifications, should be considered as part of the management plan, as recommended by guidelines 1.
- Sodium intake should be targeted at <2 g of sodium per day, and patients should be advised to undertake moderate-intensity physical activity for a cumulative duration of at least 150 minutes per week.
Monitoring and Follow-up
- Regular monitoring of blood pressure, potassium, and creatinine levels is essential, especially in advanced CKD.
- For patients on hemodialysis, volume control through appropriate dialysis dry weight assessment is crucial, often requiring adjustment of the dialysis prescription.
- Medication timing is important for dialysis patients, with blood pressure medications administered after dialysis sessions to prevent removal during treatment.

From the Research
Hypertension Management in Patients with Advanced CKD
- Hypertension is a major cause of poor cardiovascular and renal outcomes in severe CKD, making adequate control of blood pressure mandatory 2.
- The management of hypertension in advanced CKD is complex and not well defined, with few large randomized controlled trials to guide clinical practice 2.
- Current management guidelines for CKD emphasize the importance of early detection and a multidisciplinary approach to management, including blood pressure control, glycemic control, and lifestyle modifications 3.
Treatment Options for Hypertension in Advanced CKD
- Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) combined with calcium channel blockers (CCBs) may be beneficial for hypertensive patients with advanced CKD, providing better benefits on metabolic, renal, and cardiovascular outcomes 4.
- Diuretics and calcium-blocking drugs may be more effective in elderly patients with hypertension, while beta-blockers may be relatively ineffective and have more side effects 5.
- Monotherapy may not be sufficient to achieve blood pressure targets, and combination therapy may be required 5.
Considerations for Patients with Advanced CKD on Hemodialysis (HD)
- Patients with advanced CKD on HD require careful management of blood pressure and volume status to minimize cardiovascular risk 6.
- The choice of antihypertensive therapy may depend on individual patient factors, such as presence of heart failure or diabetes, and should be guided by clinical judgment and evidence-based guidelines 6.
Lifestyle Modifications and Monitoring
- Lifestyle modifications, such as dietary changes, physical activity, and smoking cessation, are important for slowing the progression of CKD and reducing cardiovascular risk 3.
- Regular monitoring of kidney function and blood pressure is essential for patients with advanced CKD, with referral to a nephrologist for patients with advanced disease or complications 3.
